What models of cnc precision machining center are there?

The cnc machining center is a high-efficiency active machine tool composed of mechanical equipment and a numerical control system, which is suitable for processing messy parts. The cnc machining center must be used when processing molds. So, what should be paid attention to when processing molds in the cnc processing center? Let's take a look with the editor of Shenzhen Ruifeng Letter Industry.

　　What should be paid attention to when machining the mold in the center of CNC precision processing factory?

　　 1. Prevent straight knife. There are two types of flat-bottom cylindrical milling cutters. One is that the end face has a top hole, and the end edge is not the center.

　　 The other is that the end face of the CNC machining center has no center hole, the end edges are connected and pass the center. When milling a curved surface, an end mill with a top hole must never go straight down like a drill, unless a process hole is drilled in advance. Otherwise, the cutter will be broken. If an end knife without a tip hole can be used to feed straight down, but because the blade's viewpoint is too small and the axial force is large, it should also be prevented as much as possible. The best way is to enter the tool obliquely downward, and then use the side edge to cut laterally after reaching a certain depth. When milling the groove surface, the process hole can be pre-drilled for cutting. Although the effect of a straight-end cutter with a ball-end milling cutter is better than that of a flat-bottomed end mill, it is best not to use this method of undercutting because the axial force is too large and affects the cutting effect.

　　 2. In the case of milled curved surface parts, if it is found that the parts have poor heat treatment, cracks, uneven arrangement, etc., the processing should be stopped in time to prevent wasting time.

3. When milling the chaotic curved surface of the mold cavity, it generally takes a long period. Therefore, the machine tool, fixture, and tool should be properly checked before each start of milling to prevent failure in the middle, affecting the processing accuracy, and even Form waste.

4. When the ball-end milling cutter is milling a curved surface, the cutting speed at the tip of the cutter is very low. If the ball cutter is used to mill a smooth curved surface straight to the surface to be processed, the appearance of the cutting edge of the ball cutter is poor, so The spindle speed should be properly increased, and cutting with the tip should also be prevented.

　　 5. When the mold cavity is milled, the file allowance should be properly controlled according to the roughness of the processing surface. Regarding the parts that are difficult to mill, if the roughness of the surface is poor, you should reserve more file allowances; and for the parts that are easy to process, such as flat surfaces and right-angle grooves, the roughness of the surface should be reduced as much as possible to reduce file work. Volume, to prevent the accuracy of the curved surface of the cavity due to large-scale file repair.

    The CNC machining center is also known as a CNC machining center. The CNC machining center is a CNC machine tool with a tool magazine that can actively replace tools, and can perform a variety of processing operations on the workpiece within a certain range. The characteristics of machining parts on the machining center are: after the machined parts are clamped once, the CNC system can control the machine tool to actively select and replace tools according to different processes; actively change the machine tool spindle speed, feed and tool movement track relative to the workpiece With other auxiliary functions, it can actively carry out multiple processes such as drilling, countersinking, reaming, boring, tapping, milling, etc. on each processing surface of the workpiece.

What are the types of CNC machining centers? The types of CNC machining centers on the market are basically based on strokes, and the types of machining centers with different strokes are different. This is also different from other manufacturers. This is based on the manufacturer’s It is determined by a naming rule of its own machining center. There is no unified standard, but mold machine tools are generally distinguished according to the stroke mentioned above, such as the 850 machining center, which means that the stroke of this machining center is 800*500* 500.
